When people are under the influence of alcohol, using glasses in bars wouldn’t be a good idea, it would actually be pretty dangerous. After what happened to their client the bar decided to switch from glasses and glass bottles to polymer ones, which don’t shatter, they are so strong that they are bulletproof. “Doctors want drinks to be served in plastic to stop 'glassing'
Up to 300 people a week are believed to be injured when glasses are used as weapons in pub brawls.” (BBC, News, Society, Health) So polycarbonate is definitely solving a big safety issue. Glass used in bars is not the only problem, imagine if all the products used by kids that are now made of polycarbonate would be made of glass. Can you even picture a baby’s bottle feeder made out of glass? That would be extremely dangerous. Also other products that are now made out of polycarbonate made it a lot safer for them, like eyeglasses or cups. The qualities of PC are superior to glass in many aspects. Some of them are that polycarbonate is lighter and thinner and it provides UV protection. PC also beats glass in the eyeglasses category. Glasses with polycarbonate lenses were introduced when lightweight, impact-resistant lenses were requested. They are more effective than the glass ones because they are less likely to fracture. An important quality about polycarbonate is that in some cases it changed the way people live and their opportunities. For example, it made working and other different activities more comfortable. Since PC eyeglasses were requested, they became the standard “safety glasses, sports goggles and children's eyewear.”
Besides a range of glasses PC also gave people other opportunities: car headlights, projection screens, helmets and visors, CDs, (CDs...

...r standards of appearance, sustainability and safety, which improves the eco-design standards. The E&E sector supports 25 million jobs and generates value added of € 135 billion.
The ‘Sustainability Concept’ is shown in the diagram above. For PC to be sustainable its long-term effect on the environment should be minimal. Polycarbonate is involved in the most important industries, creates lots of jobs, generates big amounts of money and even saves lives. The PC itself can be recycled, the only environmental problems that it causes is due to its dumping and the processing isn’t pollutant, so the environmental impact is indeed minimal. The social and economic impacts are positive as it help developing the economy and our society. As the environmental effect is minimal and the socio-economic effects are all positive PC is classified as Sustainable as the concept says.
A city that is heavily influenced by music and material possessions that has great potential to thrive as a place of attraction, yet a murder rate that ranks 3rd in the world, Detroit's biggest issue is the high demand for Cartier glasses, locally known as “buffs”. Many young men have died or have been brutally beaten for these expensive pair of shades due to popularity. The last reported death concerning this issue was in 2010 when twenty year old, Darryle Miller, was killed. The demand comes from local rappers and successful Detroit natives who have an impact on the city. These glasses are a symbol for wealth and status and that's something everyone wants coming from a city where everyone has something to prove. There isn't a specific area
Whether you have plastic or glass, concave lenses or convex lenses they are produced in much of the same way. Years ago opticians relied on separate optical laboratories to produce eyeglass lenses. However today optical outlets receive lens “blanks” (blanks received from optical laboratories) which are plastic pieces already formed to fit exactly into the front of the lens. The stages are grinding, polishing, and shaping. Materials used are plastic or glass blanks, which are thick in size to eyeglass frames, though slightly larger. Thickness may vary depending upon the prescription. Other raw materials used to make eyeglass lenses are adhesive tape, a liquid with a lead alloy base, metal, and dyes and tints. Eyeglass lenses are designed in many shapes in order to match the eyeglass frame.
Whilst working on site we wear PPE to eliminate the chances of injury. We wear protective eye glasses as we are using with tiles, when cutting and nipping them sharp bits of tile can come off and there’s a chance it could damage your eyes, in this case the glasses will prevent this happening.
There are two types of bullet resistant glass- “solid acrylic and laminated polycarbonate. Solid acrylic is just as its name suggests – a solid sheet of acrylic either 1-1/4” or 1-3/8” thick depending on the level of protection required. Laminated polycarbonate is made by layering polycarbonate, a heavy-duty clear plastic, between two sheets of glass and laminating it all together. It can be ¾”, 1” or 1-1/4” thick depending on the level of protection”. While a bullet will pierce the exterior glass layer of laminated polycarbonate, the inner
When you update the glass panes in your home, you will have more secure features. New styles of glass have improved locking mechanisms. They have impact-resistant glass. New panes can provide a safer and more secure feeling. You will benefit from the new panes that meet tough forced-entry tests.
There is also debate on how much better biodegradable plastics are in the first place. This is because as biodegradable plastics break down, they break up into smaller and smaller pieces, but never quite disappear. This leaves the potential that the plastic would continue entering the food chain. But although biodegradable plastics aren’t perfect, they are still much safer than standard plastic and present a much lower risk. In addition, by making the shift to ban single use plastics, research towards better plastic alternatives will speed up and better solutions will become available. Over time, these new alternatives to plastics may spread to other items that aren’t single use, making an even greater impact on the health of humans and the

People all over the world are wondering what can help keep their eyes protected from the sun; do sunglasses really help? The answer is sometimes, because not all sunglasses have the same amount of protection. Sunglasses could be one of the most remarkable inventions, and they have become a very popular style in today’s world. They were first made to shade one’s eyes from the light so they were composed of just tinted glass. Technology has advanced, and scientists have found out that it wasn’t the light doing all the damage, but it was UV radiation.
Even though many people say that recycling will help out our environment, they are wrong. This uniformed idea that people should continue to recycle, will only be a waste of time, since it really doesn't work. According to the article, it states, “Even the U.S. Environmental Protection Agency (EPA) says it only makes sense economically and environmentally to recycle about 35 percent of our trash.” This information proves that recycling doesn’t really work because this means not everything we use can be reused or recycled. For instance, the text also states, “Plastic provides another problem. Given the recent dramatic decline in oil prices, it is now cheaper to make a new plastic container than to recycle an old one.” To elaborate, now, people have been washing plastic in water that was heated by coal- derived electricity, which will result in more carbon in the atmosphere. The information provided, clearly proves that recycling will only be a waste of time, since it will hardly do any good to our environment. Therefore, this is an important reason that supports my position, due to recycling only being waste of time, since it really doesn’t
Sustainability is when something can be used and not be depleted, destroyed, or damaged past recovery. As we work to live sustainably, we are in effect making use of our resources in a fashion that doesn't eliminate them, and doesn't harm their source. Our resources come from the environment around us and we need to make sure that it is not harmed as we use it. According to the EPA, sustainability stems from a single principle that "Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment” (Sustainability Information). Considering this, it's obvious why we need to make sure we live sustainably and do not damage the source of our resources, our environment.
The invention of the bifocals was one of the most important inventions of the 1700s. They have changed the lives of both children and adults who have issues with their eyesight. They rid people of eyestrain and headaches. Also, bifocals rid people of the inconvenience caused by having to shift from one pair of glasses to the other. Bifocals also allow for more types of glasses to be developed.
Humans have been destroying the planet since we were able to stand on two legs. As a society, we need to work to reverse these terrible effects that our existence has on the planet. Sustainability is one way to begin reversing these effects, while still living our daily lives. In 2006, Al Gore presented his documentary, “ An Inconvenient Truth”, as a way to show the world the evidence behind global warming, climate change and the destruction of our planet. This documentary shocked the world. It was clear that changes needed to be made, but the destruction was more intense than previously thought. SInce this revelation in 2006, companies have tried to cut down on their greenhouse emissions, as well as offered sustainable products to their customers. Through a debate of morals and
Recycling is good for environment in terms of reducing illegal dumping, however, it has not much effects as for reducing the CO2 emission. Nowadays, huge amount of industrial wastes are dumped illegally. It causes pollution for environment, because those illegal dumping are thrown away into forests. Those wastes are often chemicals that is difficult to be disposed, and have bad influences to environment such as discharging poison gases by reacting with water. Companies that use such chemicals dump them because there are a few way to dispose these chemicals and it costs very much. Hence, illegal dumping would decrease if way of recycling and the costs become lower owing to entering the market of many other companies. Also recycling are considered that it can be effective to reduce CO2 emission recently, because great deal of CO2 is emitted when wastes are incinerated, but it is not much discharged in case of recycling than incineration. However recycling is not critical way to reduce CO2 emission. For example, incineration of wastes discharge CO2 at 4 stages...
The sustainability of ecosystems on which the global economy depends must be guaranteed. And the economic partners must be satisfied that the basis of exchange is equitable” (World). This quote demonstrates the complexities of sustainability. Another thing corporations should focus on when trying to be sustainable is their environmental impact. Annie Leonard in her book The Story of Stuff says that companies can significantly reduce their toll on the environment by changing their design. The design determines “the amount of energy used in making and using the product,” “the length of the product’s life span” and “its ability to be recycled” (Leonard). All these things determine the amount of resources a company must use, so simply changing a product’s design is one way a company can have a large impact on the sustainability of the environment in which it operates. One example of this is that “Wal-Mart attributed more that $100 million of its 2009 revenue to a decision to switch to a recyclable variety of cardboard in shipments” which it sells to a recycler instead of paying to send it to a landfill
Sustainability simply defined to me as balancing act between the development of sustainability is necessary for both planet Earth and humans to survive. This is reinforced in the World Commission on Environment and Development report (1987) that sustainable development must meet the needs of the present without compromising the well-being of future generations”. The Earth Charter Organization widened the idea of sustainability to respect for a culture of peace, universal human rights, nature, and economic justice (What is sustainability?, n.d.).
